Abstract
INTRODUCTION SY-009 produces a hypoglycemic effect via inhibiting sodium/glucose cotransporter 1 (SGLT1) in type 2 diabetes mellitus (T2DM) patients. This randomized, double-blind, placebo-controlled, and multiple-dose escalation clinical trial aimed to evaluate the pharmacokinetic and pharmacodynamical characteristics as well as the safety and tolerability of SY-009 in T2DM patients. METHOD Fifty T2DM patients were randomized into experimental and placebo groups, and hospitalized for 9 days managed with a unified diet and rest management. Subjects were given SY-009 or placebo from day 1 to day 7 at different frequencies and dosages. Single dose cohort was defined as the first dose on day 1 and multiple dose cohort included all the dose from day 1 to 7. Blood samples were collected for pharmacokinetic analysis. Mixed meal tolerance tests were performed. Blood samples were collected to determine glucose, C-peptide, insulin, glucagon-like peptide-1 (GLP-1), and gastric inhibitory polypeptide (GIP). RESULTS PK parameters were not obtained because blood SY-009 concentrations were below the limit of quantitation in all subjects. SY-009 decreased the postprandial glucose. Blood glucose was controlled within 4 hours after taking the drug. Short-term administration of SY-009 (7 days) had no significant effects on fasting glucose but reduced the secretion of C-peptide, insulin, and GIP and increased GLP-1 secretion. The most common adverse event was gastrointestinal disorder manifesting abdominal pain, diarrhea, and bloating. CONCLUSION Plasma exposure of SY-009 and its metabolites was fairly low in T2DM patients at doses of 1.0-4.0 mg. SY-009 reduced postprandial glucose, C-peptide, and insulin levels, showing relative safety and tolerability in the dose range of 1.0-4.0 mg. TRIALS REGISTRATION ClinicalTrials.gov Identifier: NCT04345107.

Abstract
Background Colorectal cancer is the third most common cancer worldwide. Colonoscopy is the gold standard for colorectal cancer screening. However, the colonoscopy participation rate in China is much lower than that in Europe and the United States. As only non-sedated colonoscopies are offered in colorectal cancer screening programs in China, the absence of sedation may contribute to this gap. Methods To explore the effect of free and partially participant-paid sedated colonoscopy on improving colorectal screening participation, we conducted a cross-sectional study under the framework of the Cancer Screening Program in Urban China in Xuzhou from May 2017 to December 2020. The Quanshan district was set as the control group and provided free non-sedated colonoscopy, the Yunlong district was set as a partial cost coverage group and offered partially participant-paid sedated colonoscopy, and the Gulou district was set as the full cost coverage group and offered free sedation colonoscopies. Multivariate logistic regression was used for multivariate analysis of colonoscopy participation and colorectal lesion detection rates between the groups. Results From May 2017 to May 2020, 81,358 participants were recruited and completed questionnaire, 7,868 subjects who met high-risk conditions for CRC were invited to undergo colonoscopy. The colonoscopy participation rates in the control group, partially cost coverage, and full cost coverage groups were 17.33% (594/3,428), 25.66% (542/2,112), and 34.41% (801/2,328), respectively. Subjects in the partial and full cost coverage groups had 1.66-fold (95% CI: 1.48-1.86) and 2.49-fold (95% CI: 2.23-2.76) increased rates compared with those in the control group. The adjusted PARs for the partially and the full cost coverage group was 9.08 (95% CI: 6.88-11.28) and 18.97 (95% CI: 16.51-21.42), respectively. The detection rates of CAN in the control, partial-cost coverage, and full-cost coverage groups were 3.54% (21/594), 2.95% (16/542), and 5.12% (41/801), respectively. There were no significant differences in the detection rates between the group. However, sedated colonoscopy increases costs. Conclusion Sedated colonoscopy increased colonoscopy participation rates in both the partial and full cost-covered groups. A partial cost coverage strategy may be a good way to increase colorectal cancer participation rates and quickly establish a colorectal cancer screening strategy in underfunded areas.

Abstract
Sleep duration, sleep quality and circadian rhythm disruption indicated by sleep chronotype are associated with type 2 diabetes. Sleep involves multiple dimensions that are closely interrelated. However, the sleep patterns of the population, and whether these sleep patterns are significantly associated with type 2 diabetes, are unknown when considering more sleep dimensions. Our objective was to explore the latent classes of sleep patterns in the population and identify sleep patterns associated with type 2 diabetes. Latent class analysis was used to explore the best latent classes of sleep patterns based on eleven sleep dimensions of the study population. Logistic regression was used to identify sleep patterns associated with type 2 diabetes. A total of 1200 participants were included in the study. There were three classes of sleep patterns in the study population: "circadian disruption with daytime dysfunction" (class 1), "poor sleep status with daytime sleepiness" (class 2), and "favorable sleep status" (class 3). After controlling for all confounding factors, people in class 2 have significantly higher prevalence of type 2 diabetes than those in class 3 (OR: 2.24, 95% CI 1.26-4.00). Sleep problems have aggregated characteristics. People with sleep patterns involving more or worse sleep problems have higher significantly prevalence of T2DM.

Abstract
OBJECTIVE To examine the association between isolated maternal hypothyroxinaemia (IMH) and adverse obstetric outcomes and offspring outcomes and also investigate the effects of levothyroxine therapy on IMH for the above outcomes. METHODS We systematically searched PubMed, EMBASE, and Cochrane Library, and the reference lists of key reviews were hand searched on June 9, 2021. Two authors independently screened titles/abstracts. Full articles were further assessed if the information suggested that the study met the inclusion/exclusion criteria, and two researchers performed data extraction and risk-of-bias assessment using standardized tables. Summary relative risks or the mean difference between maternal effects and offspring outcomes were calculated by a random-effects model. RESULTS We identified 38 eligible articles (35 cohort studies and two randomized controlled trials [RCT]). Meta-analysis showed that maternal IMH was associated with increased gestational diabetes mellitus, preterm premature rupture of membranes, preterm birth, fetal distress, and macrosomia outcomes in IMH compared to euthyroid women, and the relative risks were 1.42 (1.03-1.96), 1.50 (1.05-2.14), 1.33 (1.15-1.55), 1.75 (1.16-2.65) and 1.62 (1.35-1.94), respectively. IMH was not associated with placenta previa, gestational hypertension, pre-eclampsia, intrauterine growth restriction, and offspring outcomes like birth weight, low birth weight infants, fetal macrosomia, neonatal intensive care, neonatal death, or fetal head circumference. In addition, we did not find an association between IMH and adverse offspring cognitive defects. Due to insufficient data for meta-analysis, it failed to pool the evidence of levothyroxine's therapeutic effect on IMH and their offspring. CONCLUSIONS AND RELEVANCE IMH in pregnancy may relate to a few maternal and offspring outcomes. Moreover, there is currently no sufficient evidence that levothyroxine treatment during pregnancy reduces adverse maternal outcomes and disability in offspring. Further investigation to explore the beneficial effects of levothyroxine therapy is warranted.

Abstract
Background Colorectal cancer is one of the most common cancers in the world. Several studies suggest using the Asia-Pacific colorectal screening (APCS) score and its modified versions to select high-risk populations for early colonoscopy, but external validation remains rare, and which score should be selected for CRC screening in China is unclear. Validation of multiple scores in the same population might help to choose the best performing score. Methods We conducted a cross-sectional study under the framework of Cancer Screening Program in Urban China, data from asymptomatic colorectal cancer screening in Xuzhou was used to validate the APCS score, the colorectal neoplasia predict (CNP) score, the Korean colorectal screening (KCS) score, the Modified APCS score and the 8-point risk score in predicting colorectal advanced neoplasia (CAN). Results 1804 subjects were included in the analysis and 112 CAN (6.21%) was detected. In each score, the detection rate of CAN was higher in the high-risk group than in the non-high-risk group (P < 0.05), and the RR (95%C.I.) ranged 2.20 (1.50–3.22) [8-point risk] to 4.00 (2.41–6.65) [Modified APCS]. The c-statistics (95%C.I.) of the scoring systems ranged from 0.58 (0.53–0.62) [8-point risk] to 0.65 (0.61–0.69) [KCS]. The sensitivity (95%C.I.) of these systems ranged from 31.25 (22.83–40.70) [8-point risk] to 84.82 (76.81–90.90) [Modified APCS], while the specificity (95%C.I.) ranged from 43.50 (41.12–45.90) [Modified APCS] to 83.81 (81.96–85.53) [8-point risk]. Using the APCS scoring system as a comparator, the net reclassification improvement (NRI) of each modified version ranged from − 10.34% (95%C.I.: − 22.63 to 1.95%) [8-point risk] to 4.79% (95%C.I.: − 1.50% to 11.08) [KCS]. The colonoscopy resource load (95%C.I.) ranged from 9 [1–3] [8-point risk] to 11 [3–5] [APCS and Modified APCS]. Conclusions The APCS score and its modified versions have certain ability to predict the risk of advanced neoplasia and reduce the resource load. The modified APCS score and the KCS score seemed the preferable systems to classify high risk subjects based on its high RR, sensitivity and predictive ability in the selected population. Future research could focus on adding risk factors or combining with laboratory test results to improve the predictive power of the scoring system.

Abstract
Objective: To compare the application effect of the colonoscopy, fecal immunochemical test (FIT) and novel risk-adapted screening approach in colorectal cancer screening in Xuzhou population. Methods: From May 2018 to April 2019, 4 280 subjects aged 50-74 were recruited from Gulou district, Yunlong district and Quanshan district of Xuzhou. They were randomly assigned to the colonoscopy group (n=863), FIT group (n=1 723) and novel risk-adapted screening approach group (n=1 694) according to the ratio of 1∶2∶2. For the novel risk-adapted screening approach group, after the risk assessment, high-risk subjects were invited to undergo colonoscopy and low-risk subjects were invited to undergo FIT examination. All FIT positive subjects were invited to undergo colonoscopy. Colonoscopy participation rate [(the number of colonoscopies completed/the number of colonoscopies invited to participate)×100%], detection rate of colorectal lesions [(the number of diagnosed patients/the number of colonoscopies completed)×100%], colonoscopy resource load (the number of colonoscopies completed/the number of diagnosed advanced tumors) and FIT resource load in each group were calculated and compared. Results: The age of all subjects was (61±6) years old, including 1 816 males (42.43%). There was no statistically significant difference in the socio-demographic characteristics of the subjects in different screening groups. The colonoscopy participation rate was 22.60% (195/863) in the colonoscopy group, 57.04% (77/135) in the FIT group, and 33.94% (149/439) in the novel risk-adapted screening approach group, respectively. The colonoscopy participation rate was higher in the FIT group than in the colonoscopy group and the novel risk-adapted screening approach group (P<0.001). The colonoscopy participation rate of novel risk-adapted screening group was significantly higher than the colonoscopy group (P<0.001). The detection rates of advanced tumors were 6.67% (13/195), 9.09% (7/77) and 8.72% (13/149), respectively, and the difference was not statistically significant (P>0.05). The colonoscopy resource load (95%CI) was 15 (13-17) in the colonoscopy group, 11 (9-14) in the FIT group and 11 (10-13) in the novel risk-adapted screening approach group, respectively. Among them, the colonoscopy resource load of high-risk individuals in the novel risk-adapted screening approach group was 12 (9-15). FIT resource loads (95%CI) were 207 (196-218) and 88 (83-94) in the FIT group and the novel risk-adapted screening approach group. Conclusion: The combined application of risk-adapted screening approach and FIT may have a good application effect in colorectal cancer screening.

Abstract
Objective: This study aims to systematically sort out the effectiveness evaluation of the general education teaching models in epidemiology at home and abroad and provide a reference for the development and reform of epidemiology education. Methods: A systematic search of English databases such as PubMed, Embase, and Web of Science and Chinese databases such as CNKI, Sinomed, Wanfang, etc., were used to screen out the literature on different general teaching models of education in epidemiology. Each literature's teaching effect will be summarized and evaluated to conduct a systematic qualitative review in the narrative integration method, Results: A total of 45 articles (28 in Chinese and 17 in English) were included in this study, involving 14 teaching models, including mixed teaching models, PBL (problem-based learning), project designing models, and CBL (case-based learning) and other teaching models. Except for some teaching models such as project design, network platform, and flipped classroom model, the teaching effect of other innovative models is better than that of the traditional model. The distribution of teaching models was different in Chinese and foreign literature. Foreign teaching models were diverse, mainly concentrated in mixed teaching models and software/network platform learning. Domestic teaching models were relatively fixed. The mixed teaching model and PBL model were the most widely used in China, and there were fewer comparative studies between different teaching models than in foreign countries. Conclusion: General education in epidemiology is still in the early exploration stage. Compared with the traditional lecture model, the effect of various innovative teaching models has been improved. According to teaching objectives and student characteristics, we encourage extensive use of different teaching strategies, combining theoretical knowledge with practical applications and integrating epidemiological knowledge with inter-professional knowledge. Thus, students who can apply what they learn are becoming interdisciplinary talents our society needs.

Abstract
BACKGROUND AND PURPOSE SY-007 is an interfering peptide designed to disrupt the cell death signaling of phosphatase and tensin homolog deleted on chromosome ten (PTEN) nuclear translocation during ischemic stroke. Preclinical studies indicated that rats treated with 1.5 mg/kg SY-007 in the middle cerebral artery occlusion (MACO) model had significantly reduced stroke lesion size even when administered 6 h after the stroke onset. The aim of this study was to evaluate the safety, tolerability, and pharmacokinetics of ascending doses of SY-007 administered intravenously in healthy Chinese subjects. METHODS A total of 78 healthy Chinese subjects were enrolled in the single ascending dose study (1-60 mg) and received a 15-min intravenous infusion SY-007 or placebo. Plasma concentrations of SY-007 were measured by a validated liquid chromatography-tandem mass spectrometry method. Pharmacokinetic parameters were determined using non-compartmental and compartment analyses. A model based on target-mediated drug disposition was applied. Model evaluation was performed through visual predictive checks and bootstrap analysis. RESULTS Across doses of 1-60 mg, SY-007 was well tolerated. All adverse events (AEs) were mild or moderate in intensity, and all resolved without intervention. After infusion, SY-007 plasma concentrations decreased quickly with the mean terminal half-life was shorter than 0.78 h. The area under the concentration-time curve increased with a greater than dose-dependent manner from 1 to 30 mg and resulted in a dose-dependent increased from 30 to 60 mg. The nonlinear phenomenon was well described by a simplified target-mediated drug disposition (TMDD) model. CONCLUSIONS Intravenous dosing of SY-007 appears to be safe up to a dose of 60 mg. Nonlinear pharmacokinetics was observed across the evaluated doses and TMDD might be the primary reason. The effective dose of SY-007 for neuroprotective effect in patients with ischemic stroke is expected to be 10-30 mg and was recommended for the later multiple ascending dose study of SY-007.

Abstract
Objective: To explore the performance of a deep learning algorithm that combined multi-view fusion with active contour constrained for ossicles segmentation on the 10 μm otology CT images. Methods: The 10 μm otology CT image data from 79 cases (56 cases were from volunteers and 23 cases were from specimens) were retrospectively collected in the Radiology Department of Beijing Friendship Hospital from October 2019 to December 2020. An annotation of malleus, incus, and stapes were conducted. Then the datasets were established and were divided into training set (n=55), validation set (n=8), and test set (n=16). Using the rapid localization of the region of interest combined with the precise segmentation algorithm, the malleus, incus and stapes were segmented and fused from three perspectives of coronal, sagittal and cross-sectional views. Besides, an active contour loss was designed simultaneously for the segmentation of stapes. Dice similarity coefficient (DSC) was used as the objective evaluation metric for the evaluation of the segmentation results. The inter group DSC of the proposed method was compared with that of the basic method and other methods. Results: The average DSC values of the multi-view fusion segmentation algorithm for malleus, incus and stapes reached up to 94.2%±2.7%, 94.6%±2.6% and 76.0%±5.5%, respectively. After adopting the constraint of active contour loss method, the average DSC of stapes was improved (76.4%±5.4% vs 76.0%±5.5%). The visualization results also demonstrated that the segmentation results of the stapes were more complete. Conclusions: Multi-view fusion algorithm based on 10 μm otology CT images can realize accurate segmentation of malleus and incus. Combined with the constraint of active contour loss method, the segmentation accuracy of stapes can be further improved.

Abstract
Objective: To understand the current status of foreign dual-degree programs of Medical Doctor (MD) and Master of Public Health (MPH) and provide evidence-based decision-making reference for promoting the education of high-level applied public health talents in China. Methods: The list of involved institutions and information of foreign MD-MPH dual-degree programs was collected through literature retrieval, online information searching, and additional survey of key figures. We extracted the details of each project regarding professional fields, core competence, length of schooling, teaching and learning arrangement, internship eligibility, and graduation assessment. Python 3.8.0 was used for data cleaning, and the occurrence frequency of related items in each dimension was calculated. Results: A total of 99 MD-MPH programs from 104 foreign institutions were included, among which 97.1% of them were implemented in universities from the United States. The School of Public Health provided 42.4% (42/99) of the programs. Epidemiology was the major discipline set up among most programs, accounting for 12.0% (29/241) of all the specialties involved. Epidemiological research methods, health policy management and practice, and public health practice were the top 3 core competencies to be mastered. Of the 99 programs, 87 gave information on the length of the program, of which 74.7% (65/87) were five years, 6.9% (6/87) were four years, and 18.4% (16/87) included both 4-year and 5-year programs. Conclusions: The international MD-MPH programs were sophisticated and mainly organized by the School of Public Health alone or in conjunction with the School of Medicine. Epidemiology is the core course and competence objective, with a length of 4-5 years. Through learning experience from international MD-MPH programs and the Chinese unique medical development background, China should optimize its medical education system to develop a suitable talent training strategy for MD-MPH dual-degree programs in the new era.

Abstract
Abstract Objective To identify the species of common necrophagous flies in Fujian Province by gene fragment sequences of mitochondrial cytochrome c oxidase subunit Ⅰ (COⅠ) and 16S ribosomal deoxyribonucleic acid (16S rDNA), and to explore the identification efficacy of these two molecular markers. Methods In total 22 common necrophagous flies were collected from the death scenes in 9 different regions in Fujian Province and DNA was extracted from the flies after morphological identification. The gene fragments of COⅠ and 16S rDNA were amplified and sequenced. All the sequences were uploaded to GeneBank and BLAST and MEGA 10.0 software were used to perform sequence alignment, homology analysis and intraspecific and interspecific genetic distance analysis. The phylogenetic trees of DNA fragment sequences of COⅠ and 16S rDNA of common necrophagous flies in Fujian Province were established by unweighted pair-group method with arithmetic means (UPGMA), respectively. Results The flies were classified into 6 species, 5 genera and 3 families by morphological identification. The results of gene sequence analysis showed that the average number of interspecific and intraspecific genetic distance of 16S rDNA ranged from 1.8% to 8.9% and 0.0% to 2.4%, respectively. The average number of interspecific and intraspecific genetic distance of COⅠ ranged from 7.2% to 13.6% and 0.0% to 6.3%, respectively. Conclusion The gene sequences of COⅠ and 16S rDNA can accurately identify the species of different necrophagous flies, and 16S rDNA showed higher value in species identification of common calliphoridae necrophagous flies in Fujian Province.

Abstract
OBJECTIVE To estimate the prevalence rate of bone and joint injury in China and to describe the three-dimension distribution of the disease (area, time and people). METHODS Based on a cross-sectional design, a retrospective study was conducted by using Chinese basic medical insurance database from January 1, 2013 to December 31, 2017 to analyze the epidemiological characteristics of bone and joint injury. The prevalence rate of bone and joint injury in each city was calculated, and then using meta-analyses to estimate the pooled prevalence of each area and the whole country. The pooled prevalence rates were compared among the different groups of populations, in terms of geographical area, time and population characteristics (age and gender). RESULTS A total of 28 419 264 subjects were included in this study, including 705 793 patients with bone and joint injury. From 2013 to 2017, in Chinese basic medical insurance database, the overall prevalence rate of bone and joint injury was 141.5(95%CI: 90.4-203.7) per 10 000 population, and the prevalence rates of non-specific or polyarticular disease, knee disease, and shoulder disease were 101.6 (95%CI: 63.5-148.4)per 10 000 population, 22.5(95%CI:15.1-31.4)per 10 000 population and 10.9 (95%CI: 6.4-16.4)per 10 000 population. The prevalence rates varied across the areas, the highest rate was observed in North China, with the prevalence of 310.6 (95%CI: 12.6-989.7) per 10 000 population, and the lowest rate was observed in Southwest China, with the prevalence of 59.0 (95%CI: 37.5-85.2) per 10 000 population. The prevalence rate of bone and joint injury increased over the study period, from 111.1 (95%CI: 56.0-182.5)per 10 000 population in 2013 to 175.5 (95%CI: 116.8-245.5)per 10 000 population in 2017. The prevalence of bone and joint injury in the female population was 149.1 (95%CI: 94.2-215.9) per 10 000 population, which was higher than that of men [133.6(95%CI: 86.2-190.9) per 10 000 population]. The higher prevalence of knee disease, unspecified or polyarticular disease, and bone and joint injury were observed in people aged 60 years and older, while the prevalence of shoulder disease peaked in 40-59 years old people [20.6 (95%CI: 12.5-30.5) per 10 000 population]. CONCLUSION This study reported a relative low prevalence of bone and joint injury in China from 2013 to 2017. The prevalence increased over the study period, and the highest prevalence rate was observed in North China. The prevalence rate showed differences among different groups of populations, and higher rates were observed in females and people aged 60 years and older.

Abstract
Background:Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease that affects 1% of the world’s population. Several key biological functions are dysregulated in RA, manifesting clinically as pain, fatigue, and synovitis, with articular destruction, organ-based comorbidities, and functional decline. Defining immune dysregulation in the peripheral blood of patients (pts) with RA will help inform future work to assess the extent to which immune homeostasis can be therapeutically achieved for these pts.Objectives:To identify baseline molecular characteristics of the peripheral immune system, at the level of individual immune cell subsets, in pts with RA recruited to clinical trials of the oral, selective Janus kinase 1 (JAK1) inhibitor, filgotinib.Methods:Peripheral blood mononuclear cells (PBMC) were collected from 324 pts with moderate to severely active RA, who had an inadequate response to methotrexate ([MTX], FINCH-1;NCT02889796; n=109) or who were MTX naïve (FINCH-3;NCT02886728; n=215). PBMC were also collected from 50 demographically matched healthy volunteers (HV). The Immune Profiler platform was used to sort PBMC into 24 immune cell subsets, then quantify their gene expression and chromatin accessibility using RNA-seq and the assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq), respectively. Differentially expressed genes (DEGs) and differentially accessible regions (DARs) were identified among immune cell subsets from pts with RA versus HV. Gene set signature scores of Molecular Signatures Database hallmark pathways were calculated using single sample gene set enrichment analysis (ssGSEA) to examine differences in pathway activity between groups.Results:A total of 14,500 sequencing datasets were generated from the pt and HV immune cell subsets. Among these, over 26,000 DEGs and 220,000 DARs were identified in RA versus HV (false discovery rate <0.05) across the 24 immune cell subsets. DEGs were identified in all immune cell subsets tested and were most pronounced in natural killer (NK) subsets; most DARs were detected in myeloid and NK subsets. ssGSEA revealed differential pathway signaling in RA versus HV across multiple functions at the immune cell subset level. Myeloid subsets from pts with RA often showed elevated pathway activities versus HV whereas B, T and NK subsets showed a general decrease. In particular, monocyte populations from pts with RA versus HV had elevated pathway activities involved in inflammatory response and interleukin-6/Janus kinase/signal transducer and activator of transcription 3 signaling. The B, T and NK subsets showed a general decrease in tumor necrosis factor-α signaling; conversely, monocyte subsets showed an increase. Prior MTX exposure did not have a notable impact on the detected molecular profile.Conclusion:Differences in gene expression, hallmark pathway activity, and chromatin accessibility were identified in RA versus HV at the immune cell subset level. Significant contributions to differences in chromatin accessibility identified in the myeloid and NK cell populations suggest that there are more active regulatory sequences in these cell types that are associated with RA. Further investigations based on these findings may increase understanding of the immune regulatory paradigm in the context of RA.Acknowledgments:This study was funded by Gilead Sciences, Inc.

Abstract
Pharmacoepidemiology refers to the use of epidemiological research methods in studying the application and use of drugs in large populations to evaluate the safety and efficacy of medical products. Therefore, standardized pharmacoepidemiology research is the basis of the above work. Based on systematic reviews of national and international pharmacoepidemiological methodological standards and guidelines, and in combination with Chinese medical and health practice and experts' opinions, the Professional Committee of Pharmacoepidemiology of Chinese Pharmaceutical Association developed the group standard, guide on methodological standards in pharmacoepidemiology (T/CPHARMA 002-2019), to better guide the work of pharmacoepidemiology. The guideline was designed to provide advice and reference for pharmacoepidemiology research by government, regulatory agencies, research institutions, and pharmaceutical manufacturers in China.

Abstract
Objective: Percutaneous renal biopsycurrently is the most important and widely used method of renal biopsy. However, there still are some patients in whom a percutaneous approach may be considered a major risk. In these patients, renal biopsy under direct vision is a reliable alternative. We described our personal technique and experience in a series of Chinese patients who underwent retroperitoneal laparoscopic renal biopsy. Methods: We retrospectively reviewed the patients who had performed retroperitoneal laparoscopic renal biopsy over a 4-year period (Jan 2013 to Jan 2017).Forty-three patients with renal dysfunction were involved inour center.Especially some patients showed atrophic kidney and poor visualization on ultrasonography. The patients' abnormal conditions includeddialysis (10 cases), morbid obesity (5 cases), deaf-mutes (2 cases) and uncontrolled severe hypertension. The kidney was approached via alaparoscopic retroperitoneal route using athree-ports technique. Then biopsies were performed bya 16-gaugebiopsy needle, and hemostasis was achieved by compression.In less cases, a topical spray hemostatic gel was required. Results: Biopsy was performed successfully in all cases and adequate renal tissue was acquired.Mean operative time was 59.4 minutes, mean blood loss was 36.5 ml.Under general anesthesia, no anesthetic accidents and related complications were recorded. Forty-onepatients were discharged within 24 h after operation. Onepatient occurred disseminated intravascular coagulationduring operation. Red blood cell transfusion and fresh-frozen plasma infusion were performed. Injury at hilum of kidney was detected in another patient. And extrapyelogenic repair surgery was performed. Conclusions: The retroperitoneallaparoscopic renal biopsy is a safe, reliable, minimallyinvasive alternative renal biopsy method with better haemostasis, fewer complications and a rapid recovery. As the helpful supplement of percutaneous renal biopsy, this technique may have to be used more often in the future.

Abstract
Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide. Although advances have made in treatment of HCC, the overall survival rate remains low and the molecular pathogenesis of HCC is still poorly understood. The purpose of this study was to explore the molecular pathogenesis of HCC. A total of 89 patients were involved in the study. MicroRNA-93 (miR-93) was aberrantly up-regulated in HCC tissues as determined by qRT-PCR. The high level of miR-93 was closely associated with larger tumor size (p < 0.05) and poor overall survival (p < 0.05). In in vitro and in vivo assays, we demonstrated that high miR-93 levels enhanced cell growth of HCC. The luciferase activity assay showed that PDCD4 was a direct target of miR-93 and its expression was down-regulated by miR-93. Re-expression of PDCD4 inversely correlated with the level of miR-93 and attenuated the miR-93-induced promotion of cell growth in HCC. Taken together, our data indicate that miR-93 may function as an oncogenic factor in HCC, and promotes HCC cell proliferation by targeting PDCD4.

Abstract
OBJECTIVES To obtain a nationally representative Chinese three-level EuroQol five-dimensional questionnaire value set based on the time trade-off (TTO) method. METHODS A multistage, stratified, clustered random nationally representative Chinese sample was used. The study design followed an adapted UK Measurement and Valuation of Health protocol. Each respondent valued 11 random states plus state 33333 and "unconscious" using the TTO method in face-to-face interviews. Three types of models were explored: ordinary least squares, general least squares, and weighted least squares models. RESULTS In total, 5939 inhabitants aged 15 years and older were interviewed. Of these, 5503 satisfactorily interviewed participants were included in constructing models. An ordinary least squares model including 10 dummies without constant and N3 had a mean absolute error of 0.083 and a correlation coefficient of 0.899 between the predicted and mean values. Goodness-of-fit indices of two models based on split subsample were similar. CONCLUSIONS TTO values were higher in our study compared with those in a study carried out in urban areas, which is mirrored by the higher values in rural areas. Several other aspects, in addition to the valuation procedure, might have influenced the results, such as factors beyond demographic factors such as view on life and death and believing in an afterlife, which need further investigation. Future studies using the three-level EuroQol five-dimensional questionnaire should consider using this value set based on a nationally representative sample of the Chinese population.

Abstract
Objective: To investigate the clinicopathologic features of lipoprotein glomerulopathy (LPG). Methods: A total of 6 cases (5 males and 1 female, with a mean age of 27.5 years and age range of 11-53 years) of lipoprotein glomerulopathy with complete clinicopathologic data were enrolled. Except for light microscope, immunofluorescence and electron microscopic examination, renal biopsy tissues were checked by oil red O staining. The gene map of apolipoprotein E (ApoE) of 2 cases were analyzed. Results: All 6 cases presented with heavy proteinuria or nephrotic syndrome, and high level of low-density lipoprotein (LDL), very low-density lipoprotein (vLDL), ApoE. Family history of LPG was found in 3 cases, and 2 patients progressed to uremia, or even to death. Pathologic features showed that lipoprotein deposited in glomerulus capillary lumen and renal tubular epithelial cells. Gene analysis demonstrated that 2 cases expressed abnormal ApoE gene (162G>C and 455G>C). Conclusions: Lipoprotein glomerulopathy is autosomal-recessive disease with mutation of ApoE. Common clinical manifestations of LPG are heavy proteinuria or nephrotic syndrome, with a poor prognosis. Renal biopsy pathologic diagnosis can confirm this kidney disease. Emboli of lipoprotein being observed in glomerulus capillary lumen is the pathological feature of LPG.

Abstract
Accumulating evidence has indicated that Raf kinase inhibitor protein (RKIP) is involved in several intracellular signaling pathways; its abnormal expression is associated with tumor progression and metastasis in several human neoplasms. However, the role of RKIP in acute liver injury has remained elusive. In the present study, acute liver failure was induced by thioacetamide in mice, and locostatin was used to interfere with RKIP expression. It was found that RKIP expression was significantly inhibited by locostatin. Down-regulation of RKIP expression resulted in severe liver injury and extensive release of alanine aminotransferase and aspartate aminotransferase. In addition, reduced RKIP expression significantly enhanced the levels of reactive oxygen species and the content of pro-inflammatory factors such as tumor necrosis factor-α as well as interleukin-6 and −1β, and decreased the levels of nuclear factor E2-related factor-2 and heme oxygenase-1. Furthermore, down-regulation of RKIP promoted the activation of the nuclear factor-κB and extracellular signal-regulated kinase signaling pathways. In conclusion, the present study indicates an inverse correlation between RKIP level and the degree of hepatic injury, that is, a decrease in RKIP expression may exacerbate acute liver failure.

Abstract
Objective: To investigate the utilization of antibiotics in emergency departments (EDs) of class Ⅲ general hospitals in China. Methods: Data from a national monitoring network for rational use of drugs was used. The data included prescriptions of EDs from 114 class Ⅲ general hospitals in 30 provinces (autonomous regions, municipalities) of China. A total of 10 260 595 prescriptions from October 1, 2014 to December 31, 2016 were extracted. The Anatomical Therapeutic Chemical Classification/Defined Daily Dose (DDD) system was used for the classification of antibiotics and calculation of antibiotic use intensity. An auto-regression model was used to analyze the trend over time and seasonal variation of antibiotic use in EDs. Results: The rate of antibiotic prescriptions was 27.82% in EDs, among the antibiotics prescribed, 25.58% were for the combination therapy with 2 or more antibiotic agents, and injectable antibiotic prescriptions accounted for 60.59%. Besides, the number of DDDs per 100 patient visits was 81.84. Broad-spectrum agents were the most commonly used antibiotics, among which the second and third generation cephalosporins, quinolones and macrolides accounted for 23.83%, 21.68%, 19.17% and 7.89% of all prescribed antibiotics, respectively. The use of antibiotics, including prescription frequency and use intensity, in EDs had a slight but significant increase tendency (P<0.05), and the seasonal variation of antibiotic use in EDs was obvious, characterized by the highest frequency and intensity of antibiotic use in winter, the differences were significant (P<0.05). Conclusion: The antibiotic prescription rate in EDs of classⅢ general hospitals in China was controlled at a low level, but the proportions of broad-spectrum antibiotics and injectable antibiotics were high, and a significant increase trend in antibiotic use in EDs was found.

Abstract
OBJECTIVE To understand the cognition and behavior of drug safety in Beijing middle school students and provide advice for relevant education. METHODS A cross-sectional survey using paper questionnaires was carried out on the student body of nine Beijing middle schools. Multi-stage proportionate stratified cluster sampling was adopted to enroll participants. In addition to demographic questions, the questionnaire included 17 questions assessing the cognition and behavior of safe drug use, prioritizing questions that aligned with the health education guideline for primary and secondary school students from Chinese Ministry of Education. Descriptive statistical methods were applied using the SAS 9.2 software. RESULTS Of the 4 220 students investigated, 2 097(49.7%) were males and 2 123(50.3%) were females. The average age was (14.3±1.7) years. 2 030(48.1%) students were from downtown areas, 1 511(35.8%) were from urban-rural linking areas and 679(16.1%) were from rural areas. Half (51.5%) of the respondents were junior high school students, and the others were from senior high schools (34.2%) and vocational high schools (14.3%). Most of the students (89.6%) lived off campus. The awareness rate of drug safety knowledge was 74.4%, the median score of drug safety behavior was 4 points (full score was 5 points) and there was a statistically positive correlation between the two (Spearman's correlation coefficient was 0.156, P<0.001). Both the awareness rates and the drug safety behavior scores were statistically different among the students in different regions, different school types and different residence types (P<0.001). Multiple factors analysis demonstrated the correlation between the cognition degrees of both drug safety knowledge, behavior and the above factors. Of all the students, 80.4% agreed that any drug could have adverse drug reactions; 40.5% were aware that antibiotics couldn't kill viruses; as many as 49.6% mistook aspirin as antibiotic; 97.4% would read drug instructions before taking them; Only 42.4% put expired drugs into special recycling bins; 49.8% would deviate from the suggested dosage and frequency of their medication when they were sick with common diseases. CONCLUSION Overall, the cognition of drug safety in Beijing middle school students is good, but problems still exist in medication adherence, the management of expired drugs and the antibiotics cognition, which need to be fixed through specific, pointed way of education. And more efforts should be made to improve the cognition in rural regions, vocational high schools and on campus students.

Abstract
Background/Aims: Previous studies have shown that trolline possesses various forms of pharmacological activity, including antibacterial and antiviral potency. The present paper addressed the putative hepatoprotective effects of trolline. Methods: Rats received 2 ml/kg CCl4 (mixed 1: 1 in peanut oil) intragastrically twice a week for 8 weeks to induce hepatic fibrosis. The animals were then treated with trolline for additional 4 weeks. Liver pathology and collagen accumulation were observed by hematoxylin-eosin and Masson’s trichrome staining, respectively. Serum transaminase activity and collagen-related indicator level were determined by commercially available kits. NF-κB pathway activation was also examined. Moreover, the effects of trolline on hepatic stellate cell (HSC-T6) apoptosis, mitochondrial membrane potential (MMP), and autophagy were assessed. Results: Trolline significantly alleviated CCl4-induced liver injury and notably reduced the accumulation of collagen in liver tissues. Trolline treatment also markedly decreased inflammatory cytokines levels by inhibiting the NF-κB pathway. Trolline strongly inhibited HSC-T6 activation and notably induced cell apoptosis by modulating the Bax/Bcl-2 ratio, caspase activity, and MMP. Moreover, trolline significantly inhibited HSC-T6 autophagy, as evidenced by the decrease in the formation of autophagic vacuoles and the number of autophagosomes, by regulating the expression levles of LC3, Beclin-1, P62, Atg 5 and 7. Conclusion: Our study demonstrates that trolline ameliorates liver fibrosis, possibly by inhibiting the NF-κB pathway, promoting HSCs apoptosis and suppressing autophagy.

Abstract
The aim of this study was to identify the receptor for glial cell line-derived neurotrophic factor (GDNF) in glioblastoma multiforme (GBM). After GST pull-down assays, membrane proteins purified from C6 rat glioma cells were subjected to liquid chromatography-tandem mass spectrometry (LC-MS/MS). The differentially expressed proteins were annotated using Gene Ontology, and neuropilin-1 (NRP1) was identified as the putative GDNF receptor in glioma. NRP1 was more highly expressed in human GBM brains and C6 rat glioma cells than in normal human brains or primary rat astrocytes. Immunofluorescence staining showed that NRP1 was recruited to the membrane by GDNF, and NRP1 co-immunoprecipitated with GDNF. Using the NRP1 and GDNF protein structures to assess molecular docking in the ZDOCK server and visualization with the PyMOL Molecular Graphics System revealed 8 H-bonds and stable positive and negative electrostatic interactions between NRP1 and GDNF. RNAi knockdown of NRP1 reduced proliferation of C6 glioma cells when stimulated with GDNF. NRP1 was an independent risk factor for both survival and recurrence in GBM patients. High NRP1 mRNA expression correlated with shorter OS and DFS (OS: χ2=4.6720, P=0.0307; DFS: χ2=11.013, P=0.0009). NRP1 is thus a GDNF receptor in glioma cells and a potential therapeutic target.

Abstract
Objective: To evaluate the safety of Tanreqing injection among children in the real world. Methods: A multicenter, large sample, ambispective cohort study, with registration-type clinical safety monitoring. A total of 6 188 inpatients and patients from the emergency units, aged ≤ 14 years who all had been using Tanreqing injection in 59 secondary and tertiary hospitals in China, were recruited between January, 2014 and May, 2015. The main outcomes would include incidence and severity of adverse drug reaction (ADR)/adverse drug event (ADE) of Tanreqing injection. Univariate analysis was used to explain the risk factors of ADR. Results: The overall incidence of ADE was 4.20‰ (26 cases), including 4 serious ones. The incidence of ADR was 3.07‰ (19 cases), including 17 cases of general ADR and 2 cases of new ADR. All the ADR cases were mild or moderate, mostly showing damages in skin and appendages. The onset of disease happened in 24 hours after the Tanreqing injection but all the ADR cases got improved or cured. Having histories of allergies to drugs or foods would increase the incidence of ADR. Conclusion:Tanreqing injection caused low incidence of ADR in children. Progams as stratifying high-risk patients and improving administrative management could further increase the safety level of Tanreqing injection.

Abstract
A flavone was isolated from Origanum vulgare and identified as didymin (O. vulgare didymin, OVD). The protective effect and mechanism of OVD on acute liver injury was then assessed in vivo and in vitro. Our results showed that OVD significantly alleviated CCl4-induced liver injury in mice and markedly decreased serum ALT and AST activities. OVD treatment significantly reduced CYP2E1 activity, lipid peroxidation level, ROS generation, NO production and pro-inflammatory cytokines (such as TNF-α, IL-6 and IL-1β) in liver tissues and RAW 264.7 cells, but enhanced the hepatic antioxidative enzymes activities. Further study showed that OVD significantly inhibited the NF-κB and MAPK pathways. Interestingly, OVD notably enhanced Raf kinase inhibitor protein (RKIP) expression, and the effects of OVD on histological changes, oxidative stress and inflammation was largely abolished by the RKIP specific inhibitor locostatin. Our findings indicate that OVD can ameliorate CCl4-induced liver injury, which may be ascribed to its radical scavenging action, antioxidant activity, and modulation of MAPK and NF-κB signaling pathways.

Abstract
BACKGROUND/AIMS Raf kinase inhibitory protein (RKIP) is closely associated with numerous tumors and participates in their development through regulating the growth, apoptosis, invasion and metastasis of tumor cells. However, the role of RKIP in chronic liver injury and particularly in liver fibrosis is still unclear. METHODS In the present study, hepatic fibrosis was induced by porcine serum (PS) in rats and primary hepatic stellate cells (HSCs) were isolated from rat livers. Moreover, locostatin was used to interfere with RKIP expression. RESULTS RKIP expression was significantly inhibited by locostatin in both liver tissues of rats and primary HSCs. Down-regulating RKIP expression resulted in serious liver injury, extensive accumulation of collagen, and significant increase in the levels of ALT, AST and TNF-α during liver fibrosis in rats. Moreover, down-regulating RKIP significantly promoted HSCs proliferation and colony formation in vitro. Reduced RKIP significantly increased the production of collagen and the level of α-SMA as well as the expression of MMP-1 and MMP-2 in both liver tissues and primary HSCs. Furthermore, down-regulating RKIP promoted the activation of the ERK and TLR4 signaling pathways. CONCLUSION Our findings clearly indicate an inverse correlation between RKIP level and the degree of the liver injury and fibrosis. The decrease in RKIP expression may exacerbate chronic liver injury and liver fibrosis.

Abstract
BACKGROUND There is a paucity of literature available as to the relationship between different levels of each metabolic syndrome (MetS) component and decreased GFR. In the present study, we aimed to demonstrate whether MetS always plays a critical role in decreased GFR. METHODS A cross-sectional study was conducted between February 2010 and September 2012, with 75,468 adults enrolled undergoing measurements of blood pressure as well as tests of blood and urine samples. Univariate and multivariable logistic regression analyses were performed to estimate the odds ratio (OR) with 95% confidence intervals (CI), and the chi-square test was used for categorical variables and described as a percentage. RESULTS Of the 75,468 participants, 350 (0.5%) subjects met criteria for the decreased GFR, with a mean age of 48.79 ± 13.76 years. After adjustment for age, diastolic blood pressure and high-density lipoprotein were inversely related to decreased estimated glomerular filtration rate (eGFR) in multivariable analyses, with an OR (95% CI) of 0.57 (0.39-0.84) and 0.41 (0.24-0.72), respectively. The prevalence rate of CKD in critical group was 0.73% (154 of 21,127) and 0% (0 of 370) in noncritical group. In analysis stratified by the type of MetS components, the differences in noncritical group and the reference group were not statistically significant (χ(2 )=( )1.349, p > 0.05). CONCLUSIONS MetS does not always play a critical role in decreased GFR, with different levels of individual components of MetS exerting idiosyncratic effects in decreased eGFR. In fact, patients with abnormal body mass index, high triglycerides, and elevated fasting plasma glucose would not have impact on decreased GFR.

Abstract
AIM Acute kidney injury (AKI) is becoming increasingly common in hospitalized patients. A few studies have defined epidemiological data concerning hospital-acquired AKI. The aim of this study was to determine the incidence and the risk factors of hospital-acquired AKI and its treatment and prevention. METHODS A dataset of 123,105 adults who were treated in the hospital from January 2010 to December 2011, excluding patients with chronic kidney disease (CKD) and community-acquired AKI patients, was evaluated. Clinical data of blood urea nitrogen (BUN) and serum creatinine (SCr) were collected and analyzed. AKI was defined and classified according to the Acute Kidney Injury Network (AKIN). Data were compared among patients with hospital-acquired and non-hospital-acquired AKI. RESULTS Among a cohort of 123,105 hospitalized adult patients, 174 patients were identified with hospital-acquired AKI. The number of cases aged 18-39, 40-59, 60-79 and ≥80 years was, respectively, 15 (8.6%), 39 (22.4%), 82 (47.1%), and 38 (21.8%); the 60-79 years age group had the highest number. Univariate analysis showed that the unfavorable prognosis was correlated with >60 years of age, coronary heart disease, diabetes, hypotension, unconsciousness, mechanical ventilation, injuries and multiple organ dysfunction syndrome (MODS). Multivariate logistic regression analysis demonstrated that the coronary heart disease, diabetes, hypotension, mechanical ventilation and MODS were independent unfavorable prognostic factors for hospital-acquired AKI. CONCLUSION Prerenal and renal factors are the major causes of the development of hospital-acquired AKI. Thus, focusing on the potential risk factors of hospital-acquired AKI may prove to be beneficial to the prognosis of patients.

Abstract
OBJECTIVE This study was to determine the optimal dosage of ondansetron for preventing maternal hypotension during cesarean delivery. METHODS One hundred and fifty parturient women scheduled for elective cesarean section were randomly assigned to five groups (n=30). Five minutes prior to spinal anesthesia, women were injected with 5 ml of physiological saline (S), 2 mg (O2), 4 mg (O4), 6 mg (O6), or 8 mg (O8) of ondansetron in saline, respectively. Maternal blood pressure and heart rate were measured at 2-min intervals for 30 min. The serum parameters in umbilical cord blood were analyzed after delivery. RESULTS Compared with group S, the incidence of maternal hypotension was significantly lower in groups O4 and O6 (P < 0.05). The umbilical venous pH was significantly higher in group O4 (P < 0.05); while the partial pressure of carbon dioxide (Pco2) was significantly lower in groups O4, O6, and O8 (P < 0.05); and the bicarbonate (Hco3 (-)) and base excess in extracellular fluid (BEecf) were significantly lower in groups O6 and O8 (P < 0.05). Moreover, minimal changes of systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were observed in group O4 (P < 0.05). CONCLUSION The optimal dose of ondansetron preloading was 4 mg during cesarean delivery.

Abstract
When designing drug carriers, the drug-to-carrier ratio is an important consideration, because the use of high quantities of carriers can result in toxicity as a consequence of poor metabolism and elimination of the carriers. However, these issues would be of less concern if both the drug and carrier had therapeutic effects. (-)-Epigallocatechin-3-O-gallate (EGCG), a major ingredient of green tea, has been shown, for example, to possess anticancer effects, anti-HIV effects, neuroprotective effects and DNA-protective effects. Here, we show that sequential self-assembly of the EGCG derivative with anticancer proteins leads to the formation of stable micellar nanocomplexes, which have greater anticancer effects in vitro and in vivo than the free protein. The micellar nanocomplex is obtained by complexation of oligomerized EGCG with the anticancer protein Herceptin to form the core, followed by complexation of poly(ethylene glycol)-EGCG to form the shell. When injected into mice, the Herceptin-loaded micellar nanocomplex demonstrates better tumour selectivity and growth reduction, as well as longer blood half-life, than free Herceptin.

Abstract
OBJECTIVE The aim of the article was to investigate the effect of ondansetron preloading with crystalloid infusion after spinal anesthesia during cesarean delivery. STUDY DESIGN A total of 66 parturient women scheduled for elective caesarean sections were randomly assigned to two groups. Five minutes before spinal anesthesia, Group O patients were injected with 4 mg of ondansetron, while Group S patients were injected with 5 mL physiological saline. Maternal blood pressure and heart rate were measured at 2 minute intervals for 30 minutes. After delivery, umbilical cord blood samples were analyzed. RESULTS Maternal hypotension and nausea were significantly lower in ondansetron-treated patients versus placebo (p = 0.011 vs. 0.004). Umbilical venous pH was significantly higher in ondansetron-treated patients (p = 0.006), while partial pressure of carbon dioxide (Pco 2) was significantly lower (p = 0.002). Decreases in maternal systolic and mean arterial blood pressures were significantly lower in ondansetron-treated patients (p = 0.008 vs. 0.025), with less requirement for phenylephrine administration compared with controls (p = 0.029). CONCLUSION Ondansetron preloading combined with crystalloid infusion significantly reduced hypotension and nausea, while improving acid-base status, as well as reducing vasoconstrictor use.

Abstract
Hepatocellular carcinoma (HCC) is one of the most commonly diagnosed lethal cancers in the world. We previously showed two imidazolium salts (IBN-1 and IBN-9) with a moderate efficacy for HCC. Here we report a more potent imidazolium compound IBN-65 (1-benzyl-2-phenyl-3-(4-isopropyl)-benzyl-imidazolium chloride) and the associated mechanisms of action in a mouse model of HCC. The IC50 of this compound in various liver cancer cell lines was around 5 μm. IBN-65 dose-dependently arrested cell cycle at G1 phase and was associated with the down-regulation of the cyclin-dependent kinase-4, -6, cyclin D1, and cyclin E. In addition, IBN-65 induced apoptosis by down-regulating Survivin, Bcl-2 and up-regulating Bax, leading to sequential activation of Caspase-3, Caspase-9 and the cleavage of poly(ADP-ribose) polymerase (PARP). Dysregulation of the epidermal growth factor receptor (EGFR) signaling network has been frequently reported in HCC. We found that IBN-65 displayed a profound inhibitory effect on the EGFR/Raf/MEK/ERK signaling at the phosphorylation level. In Huh7 or Hep3B cells, pretreatment with IBN-65 attenuated EGF-induced phosphorylation of both EGFR and the downstream p44/42 MAPK. A siRNA knockdown of EGFR also proved that IBN-65 induced apoptosis mostly through inhibiting downstream EGFR pathway signaling, much less at the receptor level. Infrequent administration of IBN-65 (i.p., 5 mg/kg once weekly for four weeks) to mice bearing the Huh7 cells significantly reduced the tumor volume by 65% without affecting the body weight. Critically, many of the anti-tumor signaling features observed in the HCC cell lines were recaptured in the xenografted tissues. Thus, the metal-free imidazolium compound IBN-65 could be a potential candidate towards therapeutic development for HCC.

Abstract
OBJECTIVE To explore the relationship between the renal dysfunction rate and metabolic syndrome(MS), stratified by age. METHODS People took part in physical check-up in a certain tertiary hospital from March 2010 to September 2012, were enrolled in this study. Estimated glomerular filtration rate (eGFR), -a renal dysfunction indicator, was calculated by modified MDRD equation [<60 ml/min(1.73 m(2))]. Associations between the renal dysfunction rate and factors as age, gender and MS traits, were assessed by stratified analysis. RESULTS Eligible data from 75 469 subjects were used. The prevalence rates of renal dysfunctions appeared to be 0.05%,0.20%, 1.68% in 18 to 44 year-olds (youth), 45 to 59 year-olds (middle) and 60 year-olds or above (old), respectively. Participants with MS showed a significantly higher risk than those without, in the elderly only (P < 0.05)but not in the other 2 groups (P > 0.05). Participants with 2 components of MS in middle-aged, 3 or 5 components of MS in the elderly showed a significantly high incidence (P < 0.05), but no significant differences seen in other subgroups (P > 0.05). Increasing trend was not seen in all the 3 groups (P > 0.05). Elevated blood pressure (BP+) in youth and middle-aged groups, decreased high density lipoprotein (HDL-C) in middle-aged and elderly groups and elevated fasting plasma glucose (FPG+) in elderly group could all cause the abnormality rate of eGFR which showed significantly high incidence rates in the subgroup analysis (P < 0.05). The maximum of population attributable risk proportion (PAR%) was 41.91% in youth when having elevated BP. Relationship between renal dysfunction rate and triglyceride (TG)/obesity was not identified. CONCLUSION The prevalence of renal dysfunction was found low, in Xuzhou. The incidence was not associated with the numbers but might relate to the nature of certain components of MS. Increased BP showed both short-term and mid-term effects. Decreased HDL-C, however, indicated both mid-term and long-term effects. The elevated FPG only appeared long-term effects. Increased TG and obesity did not show significant effects in these observed samples. PAR% of increased BP seemed to be the most important factors which might lead to renal dysfunction.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hydrocotyle sibthorpioides (Apiaceae) have been used as a folk remedy for the treatment of fever, edema, detoxication, throat pain, psoriasis and hepatitis B virus infections in China. The aim of this study is to isolate and identify an anti-HBV compound from this herb. MATERIALS AND METHODS A compound (saponin) was isolated from the active ethanol extract using bioassay-guided screening. The structure of the saponin was elucidated by spectroscopic methods and compared with published data. The anti-HBV activity of the saponin was evaluated by detecting the levels of HBV antigens, extracellular HBV DNA, nuclear covalent closed circular DNA (cccDNA) and five HBV promoters in HepG2.2.15 cells. In addition, the levels of serum HBsAg/HBeAg, DHBV DNA, ALT/AST and hepatic pathological changes were analyzed in DHBV-infected ducks. RESULTS The chemical analysis indicated that the saponin isolated from Hydrocotyle sibthorpioides is asiaticoside. The pharmacodynamics experimental studies showed that asiaticoside effectively suppressed the levels of HBsAg/HBeAg, extracellular HBV DNA and intracellular cccDNA in a dose-dependent manner. Furthermore, experiments demonstrated that asiaticoside markedly reduced viral DNA transcription and replication by inhibiting the activities of core, s1, s2, and X gene promoters. In addition, asiaticoside markedly reduced DHBV replication without any obvious signs of toxicity. The levels of serum DHBV DNA, HBsAg/HBeAg were increased 3 days after drug withdrawal, but the levels rebounded slightly in the asiaticoside treatment groups compared with the 3TC treatment group. Moreover, analysis of the serum ALT/AST levels and the liver pathological changes indicated that asiaticoside could alleviate liver damage. CONCLUSIONS Our results show that asiaticoside could efficiently inhibit HBV replication both in vitro and in vivo, and asiaticoside may be a major bioactive ingredient in Hydrocotyle sibthorpioides.

Abstract
BACKGROUND AND AIM Hepatic fibrosis is a worldwide healthy burden associated with significant morbidity and mortality. It is caused by a variety of chronic liver injuries. There is currently no effective treatment for liver fibrosis. In this report, we tested an imidazolium salt, 1,3-diisopropylimidazolium tetrafluoroborate (DPIM), for its anti-fibrotic properties in the thioacetamide-induced mouse model. METHODS DPIM was orally delivered to the thioacetamide-treated mice via drinking water for 12 weeks at the onset of thioacetamide treatment at a concentration of 0.1% (prevention group), and for 4 weeks starting at the 8(th) week at a concentration of 0.1% or 0.2% (attenuation group), respectively. Messenger RNA and protein were determined by real-time polymerase chain reaction and Western blotting, matrix metalloproteinase (MMP) activities were measured by fluorogenic peptide substrate and zymography. Mitogen-activated protein kinase (MAPK) and PI3K inhibitors were applied in HSC-T6 cells in combination of DPIM to probe possible signal pathways underlying the compound's action. RESULTS We observed a significant reduction in collagen deposition in both prevention and attenuation groups. The α-smooth muscle actin (SMA) and transforming growth factor (TGF)-β gene expressions were also reduced in both groups. The reduction of collagen deposition could be in part attributed to the suppression of CCR-2 expression and the enhanced matrix protein remodeling by metalloproteinases, especially MMP-3. MAPK and PI3K signaling pathways may be partially participated in DPIM's molecular action. CONCLUSION DPIM reduced fibrosis in the thioacetamide-induced mouse liver fibrosis model, and warranted further studies for possible clinical application in the future.

Abstract
This study examined the effect of Asiatic acid from Potentilla chinensis (AAPC) on chronic ethanol-induced hepatic injury. Rats underwent intragastric administration of ethanol (5.0–9.0 g/kg) once a day for 12 weeks. A subset of rats were also intragastrically treated with AAPC (2, 4 or 8 mg/kg) once a day. In the end, AAPC treatment significantly protected against ethanol-induced liver injury, as evidenced by the decrease in serum alanine and aspartate aminotransferases levels and the attenuation of histopathological changes in rats. Additionally, AAPC significantly decreased blood alcohol and acetaldehyde concentrations by enhancing alcohol dehydrogenase and aldehyde dehydrogenase activities. Mechanistically, studies showed that AAPC remarkably alleviated the formations of malondialdehyde and myeloperoxidase, restored impaired antioxidants, including superoxide dismutase, glutathione peroxidase, glutathione reductase and catalase, and inhibited cytochrome P450 (CYP)2E1 activity. Moreover, the over-expression of cytokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), the elevated plasma endotoxin level and the up-regulated Toll-like receptor 4 (TLR4), CD14 and myeloid differentiation factor 88 (MyD88) as well as nuclear factor-κB were also suppressed by AAPC in ethanol-intoxicated rats. In conclusion, the protective effect of AAPC on ethanol-induced hepatotoxicity was mainly due to its ability to attenuate oxidative stress and inhibit Kupffer cell activation by decreasing the level of plasma endotoxin and the expression of TLR4, CD14 and MyD88.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Methyl helicterate is a triterpenoid isolated from Helicteres angustifolia (Sterculiaceae), one of the valuable traditional Chinese herbs. Antifibrotic activities of H. angustifolia have been extensively proved. AIM OF THE STUDY The purpose of this study was to investigate the effect of methyl helicterate (MH) on liver fibrosis in rats induced by carbon tetrachloride (CCl(4)) and to explore its underlying mechanism. MATERIALS AND METHODS Hepatic fibrosis was induced in male Sprague-Dawley (SD) rats by intragastric administration with 2 ml/kg CCl(4) (mixed 1:1 in peanut oil) twice a week for 12 weeks. To evaluate the effect of MH (16.72, 33.45, 66.90 mg/kg) on hepatic fibrosis, liver function, histological study and hepatic fibrosis evaluation were performed. Liver function was assessed by determining the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (Alb) and total protein (TP). The biomarkers such as hydroxyproline (Hyp), hyaluronic acid (HA), type III precollagen (PCIII) and laminin (LN) were examined for the evaluation of hepatic fibrosis. The underlying mechanism was investigated by measuring oxidative stress level and detecting the expression of TGF-β1 mRNA and Smad3 protein. RESULTS MH (33.45, 66.90 mg/kg) treatment significantly inhibited the loss of body weight and the increase of liver index in rats induced by CCl(4). MH also improved the liver function as indicated by decreasing serum enzymatic activities of ALT, AST, TP and Alb (P<0.05). Histological results indicated that MH alleviated liver damage and reduced the formation of fibrous septa. Moreover, MH significantly decreased liver Hyp, HA, LN and PCIII (P<0.05). Research on mechanism showed that MH could markedly reduce liver malondialdehyde (MDA) concentration, increase activities of liver superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and inhibit the expression of TGF-β1 mRNA and Smad3 protein (P<0.05). CONCLUSIONS Our findings indicated that MH can inhibit CCl(4)-induced hepatic fibrosis, which may be ascribed to its radical scavenging action, antioxidant activity, and modulation of TGF-β-Smad3 signaling pathway.

Abstract
Several lysosomal cathepsins have been implicated in a number of diseases, from arthritis to cancer. A recent member of the cathepsin family, cathepsin S (Cat S) has been associated with several types of cancer in humans. However, to date, no report has linked Cat S to human hepatocellular carcinoma (HCC). Here, we investigated the expression of Cat S in human normal and HCC livers using immunohistochemistry and Western blot analysis. The results showed that no expression or very low levels of Cat S expression were detected in the hepatocytes of normal livers. In contrast, a significant increase in Cat S expression was detected in the cancerous hepatocytes in 34 of the total 63 HCC livers (54%; P<0.01). The Cat S-positive rate was significantly higher in the HCC nodule than in the perinodular region (P<0.01). Nevertheless, the Cat S-positive rate in the peri-HCC region was still significantly higher than that in the normal liver tissue (P<0.01). Elevated Cat S expression in HCC was positively correlated with the presence of portal vein tumor thrombus (P<0.01), extra-hepatic metastasis (P<0.05) and the degree of de-differentiation (P<0.01), but was not correlated with age, the presence of hepatitis B virus surface antigen and cirrhosis, the level of serum α-fetoprotein, the number of tumor nodules, the tumor size and the clinical stage (P>0.05). Aberrant overexpression of Cat S in the cancerous hepatocytes may be one of the key events involved in HCC tumorigenesis, invasion and metastasis.

Abstract
BACKGROUND AND AIM Oxidative stress contributes to liver fibrosis through the activation of hepatic stellate cells. In a cell-based screening study, a class of imidazolium salts demonstrates anti-fibrogenic properties. Little is known on imidazolium salt mechanistic effects. We investigated the anti-fibrogenic effect of one of the imidazolium salts, 1,3-bisbenzylimidazoliumbromide (DBZIM), in a chronic mouse model of liver fibrosis and evaluated the mechanism of this treatment. METHODS Liver fibrosis was induced in mice by oral feeding of thioacetamide for 16 weeks. DBZIM was administered weekly, starting on the first day or 12 weeks from the day of thioacetamide administration. Hepatic function, histology and oxidative stress were examined. Expression of key inflammatory molecules and the molecular mechanism of DBZIM were assessed in hepatic stellate cells. RESULTS DBZIM decreased the fibrogenic response in thioacetamide-mice as measured by collagen deposition and α-smooth muscle actin expression (P<0.01). DBZIM improved liver function and reduced both oxidative damage and inflammation (P<0.01). Most importantly, our findings report the discovery that astrocyte elevated gene-1, involved in tumour progression, was up-regulated in thioacetamide-mice and DBZIM modulated astrocyte elevated gene-1 and NF-κB expression. CONCLUSION These findings indicate DBZIM is a potent therapeutic agent for the treatment of liver fibrosis.
